67 Replication BW

1. The protein helicase unwinds
the double stranded DNA.

2. The protein DNA polymerase builds
the new, single, strand
by using an original, single, strand as a template.

3. A new base is matched with a complementary base
on the original strand, like the shaped ends on our model.

4. DNA polymerase synthesizes the new single strand
piece by piece by matching up complementary base pairs.
